Ato provide for scraping across ditches or wash-outs where ordinary graders are ineffective or will not reach. 'Y

To this end the invention comprises a suitable vehicle withga'scraping blade capable of sidewise projection beyond the vehicle to substantially the entire length of the blade and the raising and lowering of the blade and the storage of the scraping members upon the vehicle for transportation.

The invention will be' best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, with the further understanding that while the Vdrawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention.. f Y Y In the drawings: Figure 1 is a. plan view of the improved scraper or grader with the scraping blade at the full laterally projected position and also showing in dotted lines the position assumed by the scraping devices when folded upon the vehicle. Fig. 2 is a sideelevation withV a portion of the vehicle Y in section. Fig. 8 is a front elevation with some parts in section and showing the scraping blade in an intermediatepositionof lateral projection. Fig. 4 is a detail of the hinge connection between the blade support and the pivot connection with, the vehicle. Fig. 5 is a view of another formof scraper blade, the view being upon a reduced scale to that of the other figures.v Y Y,

Referring to the drawings there is shown a vehicle 1 having a body portion provided with a bottom '2 and top 3 each shown as of unbroken continuity and having the sides approaching toward the front end of the vehicle, but it will `be understood that the construction of thevehicle body is not limited to such particular' formation. The bottom 2 and top 3 of the body of the vehicle are separated by spacers 4t, 5, the spacers 4E being at the rear of the body member, which in the particular construction shown is the wider end of the body member. The `usual .rear and front axles 6. and 7 are provided for the support of the body member, the front axle being held by a king bolt 8 carried by the front central portion of the body and extending through a spacing block 9 between the front of the body and the axle 7 to conform to different heights of thetwo axles from the ground. The rear. axle 6 is provided with' wheels 10 and the frontvaxle with wheels 11,' which latter, in the particular'showing of the drawings, are smaller than the rear wheels, but these are also matters which may be varied within considerable limits. In the showing of the `drawings the front axle carries a bar 12 connected to the axle by elongated bolts 13 spacing the bar sufliciently in front of the axle to avoid the wheels 11, and this bar carries swingletrees 14 for the` attachment of draft animals.

Mounted at the front end on the king bolt V8 is a swinging arm 15 comprising a top strip 16 and a lower strip 17. The arm 15 is ofA sulicient length to extend from the king bolt rearwardly beyond the rear edge of the body of the vehicle, and also rearwardly beyond the rear wheels 10, and in the particular showing of the drawings the strip 16 is arranged above the top 3 of the body and extends to the extreme rear of the arm, while the strip 17 is intermediate of the bottomV 2 and top 3 of the body, and is of less rearward extent than the strip 16, being connected thereto and spaced therefrom by an interposed block 1.8 between the rear end of the strip 17 and the corresponding portion of the strip 16. Of course, it will be understood that the arm 15 may be otherwise constructed so long as it is capable of performing the functions demanded of it, which functions will hereinafter appear.

For the purposes of the present invention the arm l'is to swing horizontally about the `king bolt 8, and to facilitate this swinging movement, so that it may be controlled from the top of the vehicle, there Vis mounted in the vehicle an upright post or shaft 19, having at its upper end a manipulating wheel lll@ Vao

20,and between the top and bottom members n of the body of the vehicle carrying a drum or' pulley 21. The post 19 with its pulley 21 is situated at one side of the body of the vehicle, while at the other side of the body of the vehicle between the top and bottom members there is journaled a pulley 22, and encircling these pulleys and extending between them is an endless chain or rope 23, one strand of which is made fast to the strip 17 of the arm 15 by a fastening device 24 which mayconsist of va. staple, eye bolt, or other device usually employed for such purpose. The post or shaft 19 carries a ratchet wheel r engaged by a holding pawl 26 on thetop of the vehicle body. By thisv means thearm 15 is movedin either direction about the "king bolt, but may be 4held in any position of adjustment toward one side of the vehicle, Jfor a purpose which will presently appear. Y Y

VFivotally connected at about the middle of its Ilength tothe rear end o1 the strip 16 of the arm 15, is a rock arm 27. This connecltion comprises abolt or pin 2S extending throughV the arml 27 about midway of thek lengthof the latter, and connected to the strip 16by strap eXtensions29 of the pin or bolt, vwhichconstitutes a pivot pin or bolt. At opposite ends of the arm 27 angle brackets 30 are made fast, and these brackets formV supports `for the opposite ends of a pintle rod 31, carrying an elongated sleeve 32 provided with a side flange 33, which sleeve and l Aflange -may correspond to one wing of a hinge. The sleeve 32 is suflieiently shorter Y. than :the ,pintle rod31 to permit a consid erable longitudinal Inovement of the sleeve 32 along the rod,while the rod and sleeve with the wing or flange 33 constitute a hinge. Fast to the wing 33 is one end member 34 of aframe35, which in the particular showing of the drawingsis a triangular iframe, but, of course,V4 may be otherwise shaped. Considering the frame 35 as a -triangular frame, there -is attached to its basic portion a scraper blade 36 carrying a suitable number,

of active or road engagingV members 37. By making ythat part of the scraper blade which .is subject to wear of several short sections,

v renewal of the partsis facilitated at a minimum cost. That end of the scraper blade remote from the'frame member or post 34 carries a plow share 33 constituting the ex! of ,draft the dirt gathered by the scraper blade mayV be'discharged at the heel of the blade. This pitch of the blade is determined bya chai-n or otherlike :connection 39 between'the outer or `plow end of the scraper blade or scraper frame and the correspond thereof is a rack segment 41 carrying at its center, by an aXis bolt or pin 42, a drum 43 Aand a latch arm 44 made fast to the drum by a pin or bolt `45, while the latch of the latch arm is in operative relation tothe teeth of the segment 41. Made fast to the drum 43 is one end oi a chain orotherflexible strand 1 -6 carried about a directioneehanging. pulleyVV 47 of the strip 16 to an eye bolt 48 or other suitable connection at the `lower portion of the heel end of the scraper frame, and this same eye bolt may be utilized for the attachment the chain or strand 40 tothe scraper V frame.

The upper edge v of the scraperblade 36is forwardly bent tohold any gathered dirt from overflowing, and this portion of the j scraper blade is braced and` supported 'by brackets 49.

Instead oi the scraper ramej35 with its blade 46, a lighter form of `frame 50 may be employed, as shown in Fig. 5, and in 4this case a scraper blade 51, also of lighter and simpler construction than the `blade36V with its renewable edge portions 37, is provided.v

Instead ofthe sleeve 32 the frame '50; isv supplied with spaced pivot eyes 52 whichV Otherwise may encircle thepintle 4bolt 31. v the structure of the `grader is the same' as already described with reference to Figs. 1 to 4, and the scraper frame'O .is simply `in-V tended asa substitute for the scraper Aframe '35 with the parts carried thereby.VV

1n the inactive position of the partsof Vthe grader the swinging ar1n'15 isso adjusted as to be somewhere near the longitudinal :mid-

dle line of the vehicle, Vand `the rock arm 27 is swung on the pivot 28 .until aboutihori-A kzontal, in whichv positionthe scraper frame,

35 with the scraper blade 36, .which together may be considered as constituting the scraper, is turned aboutthe pintle 31 as a hinged Vpintle, until the frame 35 rests ina substantially horizontal position upon 'the arml in overlyingV relation tothe body of the vehicle. In this position of the Vparts the grader is readily transported. from place to place, or may be stored ina minimum'of space.V .Y Y .A

1f now it be desired to use the grader, the

frame 35 is lifted from its resting place on the vehicle and then turned upon the'pivotV 23 until the road engaging members 37 of the blade 36 are in contact with the ground .or nearly so, actual contact, or'even a` subsurtacesposition,` bemgbrought about 'by a."

iro

suitable manipulation oflthe lever 44 causing the lowering of the blade to the'desired extent. Any lateral adjustment .of `the scraper blade is .brought about by a manipulation of the Wheel 20, which, through the shaft 19 andstrand 23 extending about the rollers 2l and 22 andfast at 24 to the arm l5, causes the latter to swing about its pivot 8 laterally of the line of travel and the scraper frame and blade participate infsuch lateral movement. Hovveveiybecause of the hinged connection 31, 32 With the arm 27 carried by the arm l5, the scraper blade maintains its lateral position With respect to the line of travel, which position may be actually or very nearly perpendicular to the line of travel, or at an angle thereto as determined by the length .of the chain. or strand 39. vSuch initially adjusted position of the scraper blade With relationto the yline of travel ismaintained Within closelimits throughout the entire swing of the arm l5 to either side of the line of draft. The range l of movement of thearm 15 is such that at one limit of movement of the arm the scraper blade is behind the vehicle so as to extendV from one. side of the vehicle to the other, and if the length of the scraper blade be about the same as the Width of the vehicle the scraper will then be located between the lines of travel of the Wheels of the vehicle. If the arm l5 be at the other limit of its movement the scraper blade is projected to substantially its Whole lengthto one side of the vehicle. This last position is advantageous Where itis desired to scrape on both sides of a ditch or Wash-out, for the vehicle may travel upon unbroken ground and the scraper be laterally projected until it spans the ditch or Wash-out. Then by aproper adjustment olf the parts the-ditch or Washout may be filled by the action of the scraper, While the vehicle itself is running upon a surface unalected bythe scraper. All this is brought about by mounting the :scraper rame or blade, `or asit may be termed the In order to regulate the depth of cut of i the outer end of the scraper blade representved by the plovv share 38, provision is made for rocking the rock arm or rocker `post 27 on the pivot 28. This may be done in sev eral diiferent Ways, and one ofthe several means for the purpose is shown in the dravvings.V Extending from a fastening `device the adjustment of the heel end of the scraper.
